The problem here is that 20.04 doesn't support g++-6. To get around this you need a multi-step process:

  1. Put a temporary repository into /etc/apt/sources.list. For me that was deb http://gb.archive.ubuntu.com/ubuntu/ bionic main universe

  2. Now you can install gcc version 6 sudo apt-get install g++-6

  3. Make that the default version sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 6

  4. Now install gfortran sudo apt-get install libgfortran3

  5. Make sure it works strings /usr/lib/x86_64-linux-gnu/libgfortran.so.3.0.0 | grep GFORTRAN*

libgfortran3 is not supported any more in Ubuntu 20.04 as it depends on an older version of gcc, which is no longer maintained in this version of the distribution. You can install a later version of libgfortran using:

sudo apt-get install libgfortran5
